Skew surge history: Wales

The seven tide gauges around the Welsh coast are exposed to three different tidal regimes. The sea level recorded at Llandudno, Holyhead and Barmouth tide gauges are subjected to the tides and weather experienced in the Irish Sea. Fishguard, on the north Pembrokeshire coast, is subject to the tide of the St. George’s Channel. Whereas on the south Wales coast the tide gauges at Milford Haven, Mumbles and Newport all record the sea level which results from the tidal forcing of the Bristol Channel and the weather systems that approach from the Celtic Sea.
